Question

1. dialysis bag experiments

. small molecules pass (water, glucose).
. large molecules stay (starch, protein).

review questions:
. 1 can starch pass through the dialysis bag?
. 2 why can glucose move through the bag?

Explanation:

1. Starch is a large - molecule. According to the information given, large molecules stay in the dialysis bag, so it cannot pass through.
2. Glucose is a small molecule. Small molecules can pass through the semi - permeable membrane of the dialysis bag due to its small size and the nature of the membrane's pore size allowing for the passage of such molecules.

Answer:

1. No.
2. Because glucose is a small molecule and the dialysis bag is semi - permeable, allowing small molecules to pass through.
